HG Sheets

Humidity & Oxygen Getters

The lifetime and performance of encapsulated devices, such as OLED displays and lighting, OPV’s (organic photovoltaics), organic and printed electronics, and implantable medical devices, are limited by their sensitivity to moisture and oxygen.  Dynic’s HG Sheets, available in a multitude of formulations to meet your specific application needs, protect your device from corrosion, degraded performance, and early failure without requiring bake-out (drying) or activation time that slows down your production process.  

You can find a quick overview of our HG Sheet products in our HG Sheet QuickReference Guide.

HD Type

Moisture getter for OLEDs & OPVs

HGSheetReels.jpg

Fast absorption of moisture in OLED's and OPV's

Moisture is often outgassed by the polymeric materials inside hermetically sealed packages like OLED's and OPV's.  Using our humidity getters gives you the best long-term reliability assurance and extends the life of your device.

  • Various form factors (thicknesses, sizes, and shapes) available
    • Total thicknesses ranging from 135-300microns
    • Sizes ranging from 4mm x 4mm to 40mm x 70mm
  • Available in both reel and sheet form to accomodate your production process
  • No activation required
  • Peel-and-stick application allows for easy installation

HD-S Type

Moisture & oxygen getter for OLEDs, OPVs, & Electronic Devices

Fast absorption of both moisture & oxygen in OLED's, OPV's, and Electronic Devices

Seal leakage, the sealing process itself, and outgassing from adhesives and materials used in electronic devices, can all cause contaminants inside your device that can lead to degeneration or early failure  Using our humidity getters gives you the best long-term realiability assurance and extends the life of your device.

  • Various form factors (thicknesses, sizes, and shapes) available
    • Total thicknesses ranging from 135-300microns
    • Sizes ranging from 4mm x 4mm to 40mm x 70mm
  • Available in both reel and sheet form to accomodate your production process
  • No activation required
  • Peel-and-stick application allows for easy installation

SF Type

Low expansion moisture getter

High Performance Type

Same great moisture absorption but in a thinner, low expansion sheet

As our electronic devices continue to get smaller, the space inside the electronic packaging is at a premium, but the need to absorb moisture does not decrease.  That's where our high performance SF type HG Sheet comes in. 

  • Various form factors (thicknesses, sizes, and shapes) available
    • Total thicknesses ranging from 100-160microns
    • Sizes ranging from 4mm x 4mm to 40mm x 70mm
  • Available in both reel and sheet form to accomodate your production process
  • No activation required
  • Peel-and-stick application allows for easy installation

LD Type

Slower acting moisture & oxygen getter

HG-SHEETReelPkg.jpg

Slower absorption of both moisture and oxygen to accomodate the manufacturing process of implantable medical devices.

The batteries inside medical devices can outgass a number of contaminants that can negatively effect the reliability of the device.  When that device is implanted in the human body, early device failure can be a matter of life and death.  Our LD type HG Sheets can protect the electronics in implantable medical devices from moisture and oxygen. 

  • Various form factors (thicknesses, sizes, and shapes) available
    • Total thicknesses ranging from 130-300microns
    • Sizes ranging from 4mm x 4mm to 40mm x 70mm
  • Available in both reel and sheet form to accomodate your production process
  • No activation required
  • Peel-and-stick application allows for easy installation
